I'm trying to change the button hover color to transparent but isn't working

Here is the code below. I’m trying to change the button hover color to transparent. the div class = "button_container" while the button class = "btn"
I changed the color initially but it isn’t working and I would appreciate any help that can be thrown my way.
Thank you in advance

I know this is mostly code I’m posting but I can’t figure it out. I believe the knowledgeable community here on Stack overflow can help me figure it out. Cheers

>Solution :

I change your opacity so you can make it as transparent. I am not sure if this is what you mean or you want the text to change the color?? If so i change it. I dont have your html so this is what I came up with Let me know.
